The sump box, which houses the sump pump, is installed inside your basement. The presence of a sump box goes a long way to relieve hydro-static pressure from beneath your basement floor.
How do sump pumps work?
- The sump box gathers trapped ground water that naturally accumulates around your foundation wall and or under your basement floor.
- The sump box has an automatic shut off, keeping water down to a manageable level.
- The submersible pump, located inside the sump box, pumps water out and away from your foundation.
- The sump operates automatically.
Here are some indications of foundation problems:
- Cracked block foundation
- Cracks in poured concrete
- Cracks in brick facing
- Chimney cracking / leaning
- Drywall cracks
- Sinking foundation
- Uneven doors / windows
Cracks can indicate that your foundation has moved. These problems must be corrected. Avoid cosmetic repairs and contact a professional. A certified foundation repair specialist is the first step in determining the cause and solutions to your problems.
Cracks are chiselled out and filled with hydraulic cement. Once cement is dry, tar is applied to the foundation wall, followed by a drainage board (Delta-wrap), preventing water pressure from building up in front of the repaired area. The weeping tile is covered up with gravel, the hole is backfilled, and earth will take time to settle back to natural state.
A weeping tile is used for water drainage near basement foundations to prevent flooding. It is a plastic material wrapped in a nylon filter cloth to prevent dirt sediment from flowing into the weeping tile.
Installation: Excavation begins in designated dig area around house. Walls are then pressure washed and cleaned of all ground materials. All cracks are chiselled out and filled with hydraulic cement. Once cement is dry, tar is applied to the foundation walls, followed by a drainage board (Delta-wrap). Next the weeping tile is installed around footings of structure, and hooked up to either a sump pump or an existing sewer connection. The weeping tile is then covered with stone, and the excavated area is back-filled.
Note that all landscape replacement should wait 4 to 6 months to allow ground to settle to its original state.
To prevent water from seeping into your basement via the window wells: install a drain. All window wells are below grade. This can make them vulnerable to flooding from trough spillover, driving rain, or snow build up against the house. Once window wells flood, the water has nowhere else to go – except into your basement! A drain installed inside your window well will provide the positive drainage required to carry water away from your foundation wall.
If your problem is a sinking, shifting or sagging foundation, you may require underpinning. This is the process of strengthening and stabilizing the foundation of an existing building or other structure. Underpinning can be your solution, for example, if the original foundation is not strong or stable enough, if the usage of the structure has changed, if the properties of the soil are inadequate, etc. This technique can be applied on everything from bridges to farm silos.
